European Schoolnet is launching a new call for teachers across Europe, to participate in the project NANOCHANNELS which just started in January 2011 and is funded under the 7th Framework Programme from Directorate-General Research.
Researchers from CNRS and the Universite de Bordeaux, in collaboration with a Chinese team, have developed the first molecular piston capable of self-assembly. Their research represents a significant technological advance in the design of molecular motors. Such pistons could, for example, be used to manufacture artificial muscles or create polymers with controllable stiffness.
Similar patterned surfaces are currently made using complex and expensive photolithography methods and etch processes under clean room conditions and used in the fabrication of many optical, electrical, and mechanical devices.
In recent years, quantum computers have lost some of their lustre. However, a new quantum algorithm, which shows how a quantum computer could be used to simulate a complex system of interacting particles, raises hopes that some of the barriers blocking the wider application of quantum computing could soon be solved.
Ein visionaeres Entwicklungsprojekt der Hochschule Karlsruhe wird ab Maerz 2011 im Ars Electronica Center vorgestellt: Teil der neuen, gross angelegten Praesentation ist auch das Projekt "Nautilos". Das Mini-U-Boot "Nautilos" soll zur Krebstherapie in der menschlichen Blutbahn eingesetzt werden und mit optischen Methoden nahezu permanent das Blut seines Traegers untersuchen.
The Rice lab of chemist James Tour reported this week in the journal Science that sputtering zinc onto multilayered graphene enabled the team to remove a single layer at a time without disturbing the layers beneath.
Gold-coated substrates of gallium nitride with specifically formed surface, developed by researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences and the Institute of High Pressure Physics of the PAS display worldwide unique properties. Thanks to these new substrates, an extremely sensitive SERS analytical technique, capable of detecting even single molecules, after decades of waiting in specialized laboratories has finally got a chance to widespread and revolutionize medical diagnostics.
Borrowing a page from modern manufacturing, scientists from the Florida campus of The Scripps Research Institute have built a microscopic assembly line that mass produces synthetic cell-like compartments.
To find our way, we use maps. Cells use "chemical maps" to find the way: they orient themselves by following concentration gradients of attractants or repellants. David H. Gracias and a team at Johns Hopkins University (Baltimore, USA) have now developed a clever new method to produce three-dimensional patterns of chemical concentration gradients in vitro - with previously unattainable versatility and precision in both space and time.
They are corrosion resistant, mechanically strong and withstand exceedingly high temperatures. With such characteristics, porous metals are generating a growing interest in numerous innovative fields of technology. They are characterised by nanostructured surfaces with pores measuring only a few nanometres in diameter. An international research team has successfully developed a heavy-duty and cost-efficient ultrasound procedure for the design and production of such metallic structures.
Infectious diseases researchers at Umea University in Sweden are studying the surface properties of bacteria together with materials scientists. Studies of the outermost parts of the cell walls of bacteria yield new information about the chemical composition of structures that are important for the capacity of bacteria to infect organisms.
After completing two collaborative training activities, both National Nanotechnology Center (NANOTEC) and Vocational Education Commission (VEC) decided to tie the knot by initiating a formal partnership agreement this afternoon at the Vocational Education Commission's office in Bangkok.
At the Association for Computing Machinery's 43rd Symposium on Theory of Computing in June, associate professor of computer science Scott Aaronson and his graduate student Alex Arkhipov will present a paper describing an experiment that, if it worked, would offer strong evidence that quantum computers can do things that classical computers can't. Although building the experimental apparatus would be difficult, it shouldn't be as difficult as building a fully functional quantum computer.
